- Clone variant: mainline U-Boot v2025.10, boot.scr, clone DTS (type5) - Initramfs splash: archr-init.c with embedded BMP, sub-second display - Panel wizard: auto-detect with fsync persistence, evdev X-button reset - Hotkeys: adc-keys volume for clone, HP jack detection, brightness persist - Boot.ini: ASCII-only (no Unicode), GPIO check removed - ES wrapper: removed framebuffer blanking (preserves splash) - Build pipeline: both variants, splash generation, panel DTBOs - .gitignore: exclude large bootloader trees and build artifacts Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# Arch R - Flash Mainline U-Boot to Clone SD Card
|
|
#==============================================================================
|
|
# Flashes mainline U-Boot binaries to an existing Arch R SD card for clones.
|
|
# Does NOT touch partitions or rootfs — only U-Boot area.
|
|
#
|
|
# Also creates a minimal boot.scr for mainline U-Boot (distro boot).
|
|
#
|
|
# Usage:
|
|
# ./flash-uboot-clone.sh /dev/sdX
|
